Wiring TIPI to the Raspberry PI

Ports

The TIPI sideport board has a port on the back that is 2x5. Looking at it from the back:

  +-----+
  |     |
  | 1 2 |
    3 4 |
    5 6 |
    7 8 |
  | 9 10|
  |     |
  +-----+

The pin functions are as followings:

• 1 - R_CLK serial latch clock
• 2 - TEST_1P
• 3 - R_RT latch select Rpi vs TI
• 4 - GND
• 5 - R_LE latch enable
• 6 - R_DOUT latch serial data output
• 7 - R_RESET TIPI Service Reset
• 8 - R_DIN latch serial data input
• 9 - GND
• 10 - R_DC latch select Data vs Control

The Raspberry PI has a GPIO header array that must be connected to the TIPI port.

The Raspberry PI connector in pin order is 40 pins, we only use the last 10. Pin 40 is closest to the USB ports.

 31 32
 33 34
 35 36
 37 38
 39 40

We connect to pins 31 through 40.

TIPI Connection to PI looks like:

TIPI	PI		PI	TIPI
1	31		32	2
3	33		34	4
5	35		36	6
7	37		38	8
9	39		40	10

PI PIN vs GPIO Numbering:

Pin	GPIO
31	6
32	12
33	13
34	GND
35	19
36	16
37	26
38	20
39	GND
40	21

Warning: connecting the cables to the +5V pins, 2 & 4, of the Raspberry PI will result in destroying the CPLD on the TIPI board.
